PUMP.

ToaZZ whom it may concern v Be it known that we, FREDERICK V. SAL- ISBURY, JOHN F. SALISBURY and AMoN C.

SALISBUR citizens of the United States,

residing at Blandinsville, in the county of MeDonough and State of Illinois, have invented certain new and useful Improvements in Pumps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to new and useful improvements in pumps, and has for its principal object to provide a pump of the double-acting type which may be easily operated and which is capable ofdeveloping considerable power in order that water may be lifted for great distances. Another object of the invention is to provide an automatic means for reversing the. movement of the pump piston which may be timed so that a number of strokes may be obtained relative to a single revolution of the pump operating wheel. v

A further object of the invention is to provide a device which may be hand or power operated at the desire of the user.

Still another and more specific object of the invention is to provide a novel form of valve for the inlet ends of the cylinders.

With these and other objects in view, th v invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which, Figure 1 is a view in elevation of a pump constructed in accordance with this invention showing a portionithereof in section to more clearly illustrate the details of construction, Fig. 2 is a view in elevation illustrating the operating mechanism on an enlarged scale, of the upper portion of the pump, Fig. 3 is a vertical sectional view through the pump cylinder illustrating the construction thereof, Fig. 4 is a sectional view taken on the line 44 of Fig. 3, Fig. 5 is a detail sectional view of a modified form of valve, Fig. 6 is a horizontal sectional view illustrating the de tail construction of the operating mechanism and automatic reversing means, Fig. 7 is a view of one of the cam wheel's, Fig. 8 is a view of-a modified. form of 0am wheel, Fig. 9 is a view similar to Fig. 8 of a Specification of Letters Patent.

Application filed May 7, 1915. Serial No. 26,579.

still further-modified form of cam wheel, Fig. 10 is adetail elevational view of a modified form of reversing gear showing a portion thereof broken away to ,more clearly illustrate the details of construction, Fig. 11 is a sectional view of Fig. 10, Fig. 12 is a detail perspective view of the sleeve used in the device illustrated in Fig. 10, Fig. 13 is a transverse sectional view through the sleeve, Fig. 14 is a view illustrating a modified form of pumppistons and cylinders, Fig. 15-,is a planview of one of the pistons used in the cylinder,

Fig. 16 is a plan view of the valve used in connection with the piston, and Fig. 17 is aplan view of the assembled pistons and valve.

, of the pipe terminates in the nozzle 6, while the lower end is secured to the connection 7 whichleads to the pump cylinders 8 and 'each end of the stem are the valve heads 15 which engage the ends of the connection 10 and close the opening on the down stroke of the pump piston. I

The modified form of valve, which is best illustrated in Fig. 5, comprises the sleeve 16 which is slidable on the stem '13 and is provided with the flange 17 against which the gasket 18 rests. A suitable washer 19 surrounds the sleeve and is held in place by means of the nut 20v which is threaded on the end of the sleeveopposite the flange 17. A suitable coil spring 21 is interposed between the flange 17 and the nut on the end'of the stem 13,- and this coil spring 1s arranged to force '9. The connection 10 which is located at 60 Inorder that the sleeve 37 will be moved the valve toward the center of the stem.

' It will thus be seen that except during the 36 on which the sleeve 37 is slidably mountsleeve 37 coiiperate.

.,1geai-T -Y46 which is rotatablyfmounted on the 3 up stroke of the pump pistons, the valve will remain closed. 7

The pump pistons, which are designated by the numerals 22, are secured to the ends of the piston rod 23 and are provided with suitable valves 24 which cooperate with the valve 12 in forcing the flow of water from the bottom of the well into the pump. The upper ends of the piston rods terminate in the angularportions 25 which are bracedby the rectangular frames 26, and these angular portions are connected at their upper terminals to the pump rods 27, which in turn terminateattheir upper terminals in the outwardly extending arms 28, to which the rack bars 29 are adjustably secured. These rack bars are provided with the teeth 30 which are arranged to mesh with the gear and pump operating mechanism which will be more fully hereinafter described.

The gear and operating mechanism hereinbefore referred to, is best illustrated in Fig. 6 and comprises the supporting arm 31 carrying the cross piece 32,,which cross piece is formed with uprights 33 in which the shaft 34 is 'journaled. This shaft 34 car.- ries the spur gear 35 and is formed intermediate its ends with the squared portion bring the clutch halves alternately into and out of engagement, and thereby alternately drive the gears 38 and 39. It will be noted that the free end of the lever 44 extends into the groove in the-cam wheel so that upon rotation thereof the lever will be oscillated. T so gears .38 and39 mesh with the crown stud 47, which stud is mounted on the upright 48 carried by the frame 32. A suitable crank 49 is secured to the face of the .gear 46 and is provided with the handle 50 by which the device is set in operation. Suitable guides 51 are mounted laterally of the gear 35 and are arranged to hold the rack bars 29 in operative relation with the gear.

1 the cam wheels illustrated in Figs. 7, 8 and 9, are provided and comprise the circular body 52 which is formed with the cam track 53. This cam track may be in the form shown in any of the Figs. 7, 8, or 9, and when the form illustrated in Fig. 9 is used, it will be apparent that the gear 42 will be shifted from one side to the. other twice during a single revolution of the crown gear 46. When the cam wheel, illustrated in Fig. 8, is used, it will be apparent that the sleeve will be shifted three times during a single revolution, and when the cam wheel illustrated in Fig. 7' is used, the sleeve will be shifted four times during a single revolution of the crank. It willthus be seen that the number of the strokes of the pump piston per revolution may. be regulated so as to.

provide a means for increasing or decreasing the speed of the movements of the pump piston without changing the speed of the drive wheel 46. These cam wheels are removably held within the crown gear 46 by means of the bolts 54, and it will thus be apparent that they are interchangeable so that any number of combinations of cam grooves may be provided.

In the modified form of the device, illus-- trated in Figs. 10, 11, 12, and 13, instead of the shaft 34 being formed with a squared portion 36, the sleeve, designated generally by the numeral 55, is provided with a suitable set screw 56 by which the same is secured to the shaft 34. This sleeve. comprises the body 57 which is formed at each end with the reduced extensions 58 Both the sleeve and the reduced portions 58 are formed with the central longitudinal opening 59 for the reception of the shaft 34, and formed in the reduced extensions 58 are the grooves 60 which aline with the longitudinal opening 61 formed in the body 57. These grooves and this opening 61 form a guide for the sliding bar 62, which is formed at each end with the lugs 63, the use of which will appear as the description proceeds. These lugs 63 extend diagonally across the outer face .of the sliding bar 62 and are arranged to movethe bar so that the reversal of the shaft will be insured. Cooperating with the sleeve and the sliding bar 62 are the clutch members 63 which are secured to the inner faces of the gears 38 in place of the clutch halves 40 described and shown hereinbefore. Each of these clutch members 63 comprises the circular body 64 which is formedwith the peripheral flange 65. These members are secured in any suitable manner to the gears, and the bodies 64 are provided with the openings 66, while the flanges 65 are formed with the internally screw threaded, screw-receiving openings 67 in which the set screws 68 are mounted. These set screws 68 are arranged to engage the lugs 63 so as to shift the bar 62 into the openings 66 when the device is in operation.

It will be apparent from the foregoing that in use when the crank .50 is turned, the

wheel 46 will be driven and thereby cause the gears 38 and 39 to revolve freely on the shaft 34 in opposite directions. 'Th'e'rotation of the gear 46 will causethe cam wheel 5 52, carried by bolts 54, to revolve andthe're by move the lever 44 so astoslidev the sleeve 37 and bring the clutch halves on thev sleeves alternately into engagement with the clu tch halves on the opposite gears, and thereby drive the shafts in opposite directions. It will be apparent that since thejgear 35 is secured to the shaft 34, the same -willbe a F alternately driven in clockwise and counterclockwise directions, thereby. causing the 1 rack bars to alternately rise and fall,.thereby operating the pump rods and pistons. During the rising of the pistons in the cylinders it .will be apparent that thevalves will be lifted from their seats and thereby. permit 39 the inflow of liquid to the cylinders.

In the operation of the modified form of reversing tgear, it will be evident that upon rotation 0 setin motion and when the of the notches in the clutch member 63 in the gear on'the' left hand side, it will be evi-" dent that the shaft will be driven in the directionof the rotation of the gear 38, until the set screw 68 in the clutch member 63',

so which is' secured to the gear 39, engages the lugs 63 on the .end of the rod 62 opposite the end adjacent the ear 38, at'which time the f rod 62 will be slid longitudinally through the grooves 60 and the opening 61 so thatli it engages in one of the openings 66 in the clutch member 63' carried by the gear 39. It will thus be seen that the direction of rotation of the sleeve and shaft 34 will be reversed so that the operation of the pump 4o 'pistons will be alternately up and down.

In the modified form of pump cylinders and piston arrangements, the two pistons are operable in a single cylinder as clearly shown in Fig. 14. he pump cylinder is designated by the numeral 69 and is provided at its lower end with the shaft 70, the lower end of which has threaded thereinto, the pipe 71 which communicates with the bottom of the well. A suitable spider 72 is 5. located in the u r end ofthe pipe and is provided with a central sleeve 73 which acts as a guide for the stem 74 of the valve 75.

, The upper end of the cylinder 69 is provided with the cap 76, having formed" therein, a central aperture 77 and a pair of outlet openings 78 in which thelower-ends of the pipes 79 are threaded. The upper ends of these pipes are connected by means of the pipe connection 80 to the stand pipe .0 81, which leads to the body of the pump. 'Slidable through thecentral opening 77 in the cap 76 is the hollow pum rod 82, the lower end of which is provided with the hollow squared portion 83 and carries the g5 pumppiston 84 which is best illustrated the gear 46, the cars 38 will be ar 62 is in one 'forcin the the upper part of tain a substantially continuous flow of water through the stand in Fig. "15'' andis formed-with three ;0 en -v ings 85 located at points equi-distant ti om each other as clearly shown. "-Slidable on the squared portion 83 of the. hollow pump rod .82; is"the valve86 .whichsis lbeshillustratedijih' "16 anid' i's' rovided with three .equi-distant 'apertures 8 .andg th'erectanguverticallythrough thecenter' of thejstand p1pe8l to the 'um operating mechanism best illustratedin 'Flgs. 1 and '2 and' this hollow pump rod may be connected in any suitable mannerv to be actuated by'the spur gears 13.5. Slidable through the hollow mp- 85 82 is the solid pump rod 89, the ower end of which is rovided with the squared portion 90 an carries the pump piston 91 which is constructed similar to the piston 84. Slidable; on the squared portion 90 of the 90 pump rod 89 is'the valve 92 which "like the valve 86 is formed with. openings which do :notregistei' with the openings in .the', isr. tons 91. Theupper end of thepumpro 89 isslidablethrough the hollow um'p rod 82 95 and: is connected in any suitab e'manner to the operating wheel 35, so thatwh'en the pump rod 82 and piston 84 descend the pump rod 89 and piston '91 will ascend; thereby iquid between the piston up throng the opening in the piston. 84 into i e cylinder69i- It will thus be seenthat a doub e actionsinglecylinder pump is provided which will mainpipe and pump when the same is in operation.-

While in the foreglqing there has been Y s shown and described t e preferred embediment of this invetion, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall withinthe spirit and scope of the ap} pended claims.
